Application filed August 16, 1916.

To all whom t may concern.'

Be it known that I, @Lor Swanson, a citizen of the United States, and a resident of Denver, in the county of Denver and State of Colorado, have invented a new and Improved Lubricator, of which the following is a full, clear, and exact description.

My invention relates to lubricators for supplying lubricant to the flanges of the wheels of railway rolling stock.

The object of the invention is to provide a simple, strong and eflieient lubricator which can be easily adjusted relative to the flanges of the wheel and which is characterized by a nozzle having a vibrator therein whereby lubricant is supplied only during the motion of the wheel.

With the above and other objects in view, the nature of which will more fully appear as the description proceeds, the invention consists in th novel construction, combination and arrangement of parts as herein fully described, illustrated and claimed.

In the accompanying drawings, forming part of the application, similar characters of reference indicate corresponding` parts in all the views.

Figure 1 is an elevation of the lubricator, the lower part of which is in section to show the details of construction;

F ig. 2 is a fragmentary section ofthe lubricant container and an elevation of the means for securing the lubricator to the rolling stock; and

Fig. 3 is a modified structure of the lubricant container of thelubricator.

Referring to the drawings, 5 is the lubricant container which carries a strainer 6 flanged at the top, the flange serving as means for clamping the strainer within the container through the medium of a cap 7 having a cover 8 through which lubricant may be introduced into the strainer. The strainer is preferably filled with some hairy material 9. The body of the strainer has a number of apertures screened by suitable fabrics 10 through which lubricant passes into the container 5 from where it finds its way into the inlet chamber 11 of the valve casing 12. The outlet chamber 13 of the valve casing has an extension 14 adjacent the bottom thereof.

A distributing nozzle 15 is threaded into the extension 14. The bore 16 of the nozzle is engaged by a pin 17 the head 18 of which lies Within the extension la the length Specification of Letters Patent.

of which pin extends the length of the bore 16. The pin carries a frustocone-shaped washer 19 adjacent the head thereof, and which is separated from the inner end of the nozzle 15 by a pliable washer 2O provided on the pin. rl`he washer 20 is preferably of a diameter substantially equal to the smaller diameter of the frustocone-shaped washer 19 in juxtaposition of which it lies.

The outer end of the nozzle 15 has a depending portion 21 which is recessed in the face thereof to receive a fibrous member 22 of wood or other suitable material. The face of the nozzle is slightly oblique to the bore 16, being narrower at the upper part thereof, so that the fibrous part of the nozzle engaging the flange 23 of the wheel of rolling stock provides a clearance between said flange and the upper part of the nozzle. Consequently the extremity of theV pin 17 projects slightly out of the nozzle to engage the flange. W hen the wheel is rotated the pin. is caused to vibrate in the bore 16. In consequence the washers 19 and 2O are displaced on the pin and oil is allowed to pass into the bore. The oil in the bore is carried by the pin to the face of the nozzle from where it will flow to the fibrous member 22 which transmits the lubricant to the flange through the friction with the flange.

rJ'he container 5 has a lateral pin 24 which is clamped to the body of the container so that the pin may be adjusted along the container. The pin 2li bears in the sleeve of av socket 25 which is slidably and revolubly mounted on an arm 2G of4 a bracket 27. The bracket is secured to the rolling stock above the wheel thereof. The socket may be clamped to the arm by means of set screws in any desired position. It will be noted that the suspension of the container is such in the socket 25 that the same is free to swing gravitationally to and from the flange 23 of the wheel. A portion of the pin 24 eXtends through the sleeve of the socket in which it bears, and thereat a coil spring 27 is provided. The spring is compressed between the sleeve and a washer on the pin, so that normally said spring prevents a. longitudinal movement of the pin within the sleeve of the clutch. The spring prevents the displacement of the nozzle by the Inoving wheel, and therefore the feed of oil to the tread of the flange.

The valve casing 12 at its juncture with the COntaner has preferably avpassage which is in communication with a conduit 30 through which a hot medium may be circulated to increase the fluidity of the lubricant fed by the lubricator.

Vhen heavy oils are utilized for lubrication, the valve casing may be dispensed with and a conduit 31, for increasing the fluidity of the lubricant in the container, can then be passed directly through the container' to discharge into a chamber 32 to which the nozzle 15 is connected. The lubricant from the container 5 is fed to the chamber through an aperture 33 formed in the conduit 31 adjacent the bottom of the container 5. The aperture is engaged by a pin 34 of a, smaller diameter than the aperture so that the pin may vibrate therein and facilitate the flow of the lubricant'J through the clearance.

I claim:

1. A lubricator comprising` a lubricant container, a discharge nozzle therefrom` a filler of ibrous material carried by the nozzle and adapted to contact with the surface to be lubricated, and a member free to vibrate in the nozzle lying in the path of the flow of the lubricant, said member also adapted to engage the surface to be lubricated.

2. A lubricator comprising a lubricant container, a nozzle, a fibrous iiller on the surface of the nozzle adapted to conta-ct with the surface to be lubricated, and means free to vibrate in the nozzle adapted to supply lubricant to the face of the nozzle.

3. A lubricator comprising a lubricant container, a discharge nozzle therefor havn ing a bore through which lubricant is to be discharged, a pin in the bore mounted to slide and turn in the bore and adapted to project through either end of the bore, a washer free to move on said pin for engaging the inner end of the bore of the nozzle and adapted to prevent flow through the bore when the pin is not disturbed.

Ll. A lubricator comprising a lubricant container, a nozzle, a fibrous filler on the surface of the nozzle adapted to contact with the surface to be lubricated, means free to vibrate in the nozzle, and means for preventing the flow through the nozzle carried by said means adapted to vibrate.

5. A lubricator comprising a lubricant container, a discharge nozzle therefor having a bore through which the lubricant is discharged, a librous filler on thc surface of the nozzle adapted to contact with the surface to be lubricated and located below the bore of the nozzle, a pin loosely mounted in said bore and adapted to project through either end of the nozzle, and a washer free to move on said pin and adapted to engage the inner end oi' the nozzles bore, the outwardly projecting end of the pin being adapted to come in contact with the surface to be lubricated whereby the same is set into vibration substantially as and for the purpose set forth.

(j. A lubricator comprising a lubricant container, means for pivotally supporting the container, and yielding means associated with Athe supporting means of the container whereby a movement of the container at right angles to the swinging plane is re sisted.

7. A lubricator comprising a support, a lubricant container, a pin associated with the container and mounted to rotate and slide in said support, and a spring associated with said pin and support for preventing the slidable motion of said pin in the support.
